There are some methods to fertilize cotton at flower bud stage.
After budding, cotton entered the period of vegetative growth and reproductive growth, but still dominated by vegetative growth. During this period, it is necessary to set up a shelf for high cotton yield and fully supply the demand for cotton fertilizer at the bud stage, not only to meet the needs of cotton plants, but also to prevent excessive fertilization, resulting in cotton plant growth. For the cotton fields with low amount of base fertilizer, some mature manure and cake fertilizer can be applied at the bud stage, or a small amount of available nitrogen fertilizer can be mixed and deeply applied to make the fertilizer decompose gradually, play a role in the flower and boll stage, and spray new high-fat film at the right time, which can greatly improve the effective component rate of fertilizer.

Technology of rational fertilization for Cotton
Popularizing the scientific fertilization technology of cotton is an important measure to improve the yield per unit area and product quality of cotton field. The requirement and fertilizer application technology of ammonia, phosphorus and potassium in cotton the results of field fertilizer experiment showed that for every 100 kg seed cotton, pure nitrogen, phosphorus pentoxide, potassium oxide and nitrogen: phosphorus pentoxide: potassium oxide were 5.0 kg, 1.8 kg, 4.0 kg respectively. Rational application of base fertilizer. Base fertilizer should be based on organic fertilizer, combined with a certain proportion of chemical fertilizer. Generally use pig and cow manure per mu

Fertilization techniques for High yield of Cotton
Fertilization is the most important and active link in cotton production. In order to obtain high yield of cotton, scientific fertilization must be achieved. The lint yield of Diandong and Sunwan villages in Tongshan County, Jiangsu Province has steadily exceeded 1500kg/hm2 for more than ten years in a row. According to the investigation, the author sums up his main experience in fertilization into three words, that is, "sufficient, early and complete". The main results are as follows: 1 "sufficient" sufficient fertilizer is the basis of high yield. That is, the target yield is determined according to the production conditions and management level, and the sufficient amount of fertilizer application is determined according to the target yield. According to the experience of the above-mentioned high-yield units, it is necessary to obtain an order.

Rational fertilization methods for Cotton
Re-apply flower and boll fertilizer. The flowering and boll stage is the most exuberant period in cotton life, and the vegetative growth and reproductive growth of cotton are at the peak, and the most nutrition is needed. timely supplement of fertilizer plays a key role in promoting cotton peach, preventing premature senility, producing more three peaches and increasing boll weight. In fertilization, the cotton plant should not grow too long, and the cotton field with high fertility and vigorous plant growth can be fertilized late, which can be postponed to 1 or 2 big peaches in the lower part of the plant at full flowering stage, while in the cotton field with low fertility and weak growth, flower and boll fertilizer should be re-applied early in the early flowering stage. Urea is usually applied per mu in mid and late July.

High cotton yield by scientific fertilization
It is common to apply a lot of fertilizer in cotton planting, but the cotton yield decreases. This is because farmers do not understand the law of fertilizer demand for cotton and fertilization is unreasonable, which not only wastes fertilizer, but also results in low yield and poor quality of cotton. Cotton farmers should master the following points in fertilization: first, select the types of fertilization: on the basis of nitrogen fertilizer, increase the amount of phosphorus and potassium fertilizer, in order to enhance the disease resistance of cotton, prevent premature senescence and improve cotton yield. Second, determine the reasonable amount of fertilizer application: it is best to combine the soil testing formula fertilization technology.

Scientific fertilization can reduce cotton bud and boll shedding.
The vegetative growth (root, stem, leaf growth) and reproductive growth (bud, boll, boll growth) of cotton are not coordinated, resulting in the imbalance of the supply, transport and distribution of photosynthates in cotton plants, which is an important reason for the shedding of cotton buds and bolls. Through comprehensive measures centered on fertilization, controlling cotton growth is an important means to reduce cotton bud and boll shedding. Practice has proved that controlling the stem and leaf growth of cotton in the early stage, setting up a high-yield shelf in the middle stage to make it grow steadily and preventing premature senescence in the later stage is an effective way to reduce the shedding of buds and bolls in the middle and lower parts. Therefore, in addition to reasonable close planting, strengthen the water

Strengthening foliar fertilization to improve the boll rate of cotton
The ripening of summer crops in Haimen City has been delayed due to the influence of climate this year, and it has been in a state of drought since the summer harvest, and it did not rain heavily for several days until mid-July. The weather conditions before drought and rain are very disadvantageous to the living and growing plants that have been postponed transplanting cotton, and the growth process is about 10 days later than usual. In order to improve the rate of bud formation and boll formation rate in the later stage of cotton, it is suggested that foliar fertilizer spraying should be used to strengthen fertilization management in the later stage. 1. Grasp the rhythm of fertilizer in combination with pest control. Not every pest control has to be added.

Fertilization Technology of Cotton in Huang-Huai-Hai region
1. The main problems in Huang-Huai-Hai cotton area are generally high amount of nitrogen and phosphorus chemical fertilizer, insufficient application of organic fertilizer, large amount of base fertilizer, insufficient topdressing fertilizer, and lack of trace elements boron and zinc. two。 The principle of fertilization (1) increase the application of organic fertilizer and advocate organic-inorganic cooperation. (2) according to the conditions of soil fertility, properly adjust and reduce the amount of nitrogen and phosphorus fertilizer, apply potassium fertilizer reasonably, and pay attention to the combined application of boron and zinc. (3) nitrogen fertilizer should be applied in stages and appropriately increase the proportion of nitrogen fertilizer in the middle stage of growth. (4) Fertilizer application should be related to high yield and high quality.

Cotton is fastidious because of seedling fertilization at flowering and boll stage.
In June, there was frequent plum rain after cotton budding in Hubei cotton area. coupled with the differences in field management, the cotton growth progress was inconsistent. The cotton with earlier development has produced 1 or 2 peaches per plant, while the cotton with late development has just budded, and the difference in development progress is 20 to 30 days. Therefore, different measures should be taken in cotton fertilization management. Judging from the cotton seedling situation investigated in the field, Wang Hua, the 5th squadron of Nihu Battalion of Diaodong Farm in Hanchuan City, showed that half of the 26 mu cotton leaves were obviously short of potash fertilizer. It was suggested that he should make up immediately.

Application of Tea Cake in Aquaculture
Tea cakes contain hemolytic tea saponins, 11%-16% crude protein, 5%-7% fat, 40% digestible sugar, 11% nitrogen, 0.37% phosphoric acid, 1.23% potassium, and a variety of essential amino acids for animals. It is widely used in aquaculture. ① medicine pond is rich in water. Tea cake is the preferred pond cleaning agent for fish, shrimp and crab mixed culture ponds. The method of medicine pond is as follows: in the pond with water depth 30~50cm, the tea cake is crushed 25kg / hm3; the pond with 1m water depth can be increased to 50k.
